I have 2 computers on a network (cpu1 and cpu2) that I am using for data collection and then several computers that I am not using. When I made a shared variable in LabVIEW, I made it a "network published" one. After those variables are deployed on cpu1, I go to cpu2 modify the shared variable in another VI by allowing aliasing, and then browsing for the PSP address. For some reason I cannot see cpu1 at all, but I can see the rest of the network!
When I go back to cpu1 and try to browse for a PSP address, I can see cpu1, and the deployed variables, but I cannot see cpu2 on the network (although I can see all of the other computers)! I know they can see each other, I pinged one of the IP addresses from the other and it had 0ms delay. If you have any suggestions for what to try, I'm up for it! Thanks!

how's your firewall configuration?

Hmm... all I know is that it is enabled, I'm not sure exactly what the configuration is. Should I try disabling it?

It probably would have taken the same amount of time to just try it instead of asking. 🙂
Yes, as a quick test disable the firewall and see if it makes a difference. This will at least narrow down the problem.

Haha, I would have to suit up for the clean room first, so I will try it next time I go there!

I was able to see the other computer after the firewall was down! I did some searching for what programs to add to the firewall exceptions when you want to use shared variables. Unfortunately, even though I could see the other computer, the shared variable was not visible. I tried restarting the NI variable engine from command line, but it said that the process was not accepting commands at the moment. I have not quite ironed out the networking...
